This doesn't look good - a stack corruption somewhere in the X
library.  The stack is probably already corrupted in those weird
looking type converter warnings. Since it used to work with X11R6.99,
I'd say it's a problem with that X version and/or cygwin ... I must
admit that I'm still running an ancient version of X.org (on ancient
hardware ;-) and I'm afraid of upgrading, so I haven't tested it
with X11R7.4 yet. Maybe you could forward this to the cygwin
developers, they might be in a better position to debug this.

Best regards,
Stefan
